Definitions

  • the present invention relates to an apparatus for cutting workpiece having at least one plane surface and for processing the edges of the cut piece parts.
  • the invention is based on the problem of simplifying the cutting of a plate-shaped starting material and the processing of the edges of the cut piece parts.
  • the inventive apparatus is primarily intended for cutting plate-shaped workpieces. However it can also be used to cut other workpieces and process their edges. The only essential point is that the workpiece have at least one plane surface with which it lies against the rams.
  • the plate-shaped receiving means can be of right-angled design. Its size depends on the size of the plate-shaped starting material out of which the workpieces are cut. For marble and other stone slabs it is Generally sufficient to use a plate-shaped receiving means with a length of two to four meters and a width of one to two meters. The size of the plate-shaped receiving means depends on the size of the rough slabs to be processed.
  • the rams are expediently distributed uniformly over the plate-shaped receiving means. They can thus be disposed on the plate-shaped receiving means in a grid shape, i.e. at the intersecting points of right-angled coordinates, or along parallel diagonal lines or along concentric circles or in some other Grid or pattern.
  • the distance between the rams depends on the size of the smallest piece part. That is, the distance between the rams must be such that at least three rams attack even the smallest piece part so that it is safely borne by the rams and can be reliably pushed out by them from the rest of the plate-shaped starting material or the adjacent piece parts cut out of the plate-shaped starting material, thereby exposing its edges for processing by the edge processing tool.
  • the rams have a nonslip design at their ends attacking the workpiece so that the latter is fixed reliably on the rams during cutting and edge processing.
  • Firm adhesion of the workpiece to the rams can be obtained by providing the end of each ram with a suction cup to be subjected to underpressure, or with a nonslip rubber support.
  • a suction cup to be subjected to underpressure, or with a nonslip rubber support.
  • magnetic holders For processing metal plates one can also use magnetic holders, and for soft materials such as wood or plastics one can use points that penetrate the plate surface.
  • the plate-shaped receiving means is generally disposed horizontally, i.e. formed as a table, in particular in the case of heavy workpieces.
  • the plate-shaped receiving means can be disposed vertically.
  • the plate to be cut and the cut workpieces must likewise be held by the rams in a vertical position, which can be achieved for example if the rams bear suction cups to be subjected to underpressure. Suspended processing with the workpiece disposed below is also conceivable.
  • the inventive apparatus preferably cooperates with a computer- or numerically controlled machine tool for cutting the workpiece and processing the edges of the piece parts.
  • the apparatus can also be operated manually, e.g. via a control panel.
  • the rams of the inventive apparatus and the machine tool can thereby be controlled jointly by the same computer. If several piece parts are cut out of the starting plate and their edges processed with the computer-controlled machine tool, it suffices to align the machine tool with only one reference point on the starting plate.
  • the working head of the machine tool can be fitted with various tools, for example an end-milling cutter, drills and profile cutters for different edge widths and profiles, and grinding and polishing tools.
  • the cutting of the piece parts out of the starting plate can be optimized by CAD.
  • the rams of the inventive apparatus can be controlled singly, i.e. moved in and out singly, so that the piece part whose edges are to be processed can be moved out from the remaining plate or the other cut workpieces disposed around it far enough for the edge processing tool of the machine tool to be able to process its edges without being impaired by the remaining plate.
  • the rams can for this purpose be designed as rods that are mounted in bearing bushes provided on the plate-shaped receiving means. However it is also possible to design the rams as threaded spindles.
  • the operation of the rams can be e.g. pneumatic, hydraulic or electric.
  • the inventive apparatus preferably has a plate-shaped slide movable with respect to the receiving means on the side of the receiving means facing away from the workpiece for moving the rams from the moved-in to the moved-out position. Furthermore, a singly drivable locking means is provided for each ram. To move the rams attacking the cut piece part into the moved-out position, all rams and the slide can first be moved out toward each other by moving the receiving means.
  • the locking means attacking the cut piece part whose edges are to be processed are then operated, whereupon the receiving means and the slide are moved away from each other so that the rams whose locking means have not been operated are moved back into the moved-in position, for example by gravity or a spring or the like.
  • each ram is lockable in the moved-out position by the corresponding locking means when it has been pressed out of the plate-shaped receiving means by the lift of the plate-shaped slide or the lowering of the receiving means by the slide.
  • the motion of the rams with the plate-shaped slide has the advantage that all rams bearing the workpiece whose edges are to be processed are moved out the same distance.
  • the rams When starting plates of difference thicknesses are used it is possible to give the rams a telescoped design. With natural stone slabs it is frequently the case that the two surfaces do not extend parallel but the slab is thinner at one end than at the other. In such cases the stone slab is preferably placed on the rams with its visible side, i.e. its polished side, so that the edge profile cutter produces a perfect edge profile joining the polished surface.
  • a plate-shaped stop that is parallel to the plate-shaped receiving means i.e. horizontal
  • a plate-shaped stop that is parallel to the plate-shaped receiving means i.e. horizontal
  • the starting plate is pressed with the rams in such a way as to be aligned horizontally with its visible side.
  • FIG. 1 shows a schematic perspective top view, with broken away parts, of the plate-shaped receiving means of the apparatus with several cut piece parts and one piece part being processed on the edge with a tool;
  • FIG. 2 shows a cross section through a side portion of the apparatus
  • FIG. 3 shows a cross section through two differently designed rams
  • FIG. 4 shows two different cutters on the piece part.
  • a slab 2 e.g. made of marble is placed on a plate-shaped receiving means 1 formed as a table.
  • Working head 3 of a computer-controlled machine tool not shown in any detail is disposed above slab 2 so as to be movable in the X, Y and Z directions.
  • Working head 3 is fitted with several tools 4, 5 that can be swiveled into their working position by rotation about axis 6, whereby tool 4 swiveled into its working position in FIG. 1 is a profile cutter.
  • washstand top 8 is provided with a round opening 10 and a bulge 11 on one longitudinal edge in the area of opening 10.
  • piece part 8 (the washstand top) is raised above slab 2 and adjacent piece parts 7 and 9 such that profile cutter 4 can process outer edges 12 and inner edge 13.
  • part 8 must be raised at least by the height of edges 12, 13, i.e. at least thickness a of slab 2.
  • plate-shaped receiving means 1 is provided with a multiplicity of uniformly distributed rams 14, 14'. While piece part 8 raised from slab 2 is disposed on moved-in position. Piece parts 7, 8, 9 need not be raised successively for their edges to be processed; spaced apart piece parts, such as parts 7 and 9, can also be raised simultaneously by rams 14 disposed therebelow since perfect edge access for tool 4 is still ensured then.
  • nonlocked rams 14 move back into the moved-in position when slide 17 is lowered, as illustrated by ram 14 shown on the left of FIG. 2.
  • Plate-shaped receiving means 1 is supported by feet or side walls 27 on a base plate 28 on which lifting means 18 is also mounted.
  • each ram 14 has a lifting means 18' associated therewith.
  • FIG. 4 shows on the left an end-milling cutter 5 and on the right a profile cutter 4 and the edge of the workpiece.
